The United States military's ORS-3 mission is slated to blast off Tuesday night (Nov. 19) carrying 29 different satellites — the most ever in a single launch, mission officials say.

ORS-3 is scheduled to lift off atop a Minotaur 1 rocket from NASA's Wallops Flight Facility in Virginia between 7:30 p.m. and 9:15 p.m. EST Tuesday (0030 and 0215 GMT Wednesday) in a launch that should be visible from much of the U.S. East Coast, weather permitting.
